Simple compound commands—such as stringing several commands together in a sequence on the command line—are used often. Such commands are separated by semicolons, which define the end of a command. To create a simple series of shell commands on a single line, simply separate each command using a semicolon, like this:

I've never held a job as a developer nor in operations—so what am I doing writing an article about DevOps? I've always been interested in computers and technology. I also have a passion for people, psychology, and helping others. When I first heard about DevOps, the concept piqued my interest, as it seemed to merge many of the things I was interested in, even if I don't write code.

Software-defined networking (SDN) is a dynamic, manageable, cost-effective, and adaptable networking technology suitable for the high-bandwidth, dynamic nature of today’s applications. By using an SDN architecture, an IT operations team can control network traffic in complex networking topologies through a centralized panel, rather than handling each network device, such as routers and switches, manually.

Machine learning and artificial intelligence (AI) are some of the hottest buzzwords around, especially in the open source community. It seems that every month brings a new machine learning system, each focused on a different application.

How many gigabytes of data did we (the people of Earth) create yesterday?

...brain. is. thinking...

More than 2.5 billion!

And it's growing. Yes, it's hard for us to wrap our human brains around it. So, the question the Command Line Heros podcast deals with this week is: How do we handle and use such enormous amounts of data?

More and more data is mind-boggling but also exciting. We have the potential to do so much with so much data... with computers doing the hard work.

I teach a traditional "get to know college" course for freshmen. It's designed to help new students work on the skills they'll need to be successful in college, such as time management, personal management, and communication.

It's also become a prime opportunity for me to introduce freshman students to the guiding principles of open culture.

I've developed a method for treating my class as an open organization. To create a more collaborative and inclusive environment, I let the students co-construct the official course syllabus.

For most people (especially non-techies), the act of writing means tapping out words using LibreOffice Writer or another GUI word processing application. But there are many other options available to help anyone communicate their message in writing, especially for the growing number of writers embracing plaintext.

Python is an amazing language. In fact, it's one of the fastest growing programming languages in the world. It has time and again proved its usefulness both in developer job roles and data science positions across industries. The entire ecosystem of Python and its libraries makes it an apt choice for users (beginners and advanced) all over the world. One of the reasons for its success and popularity is its set of robust libraries that make it so dynamic and fast.

Over the 10+ years I've been involved with open source, I've been part of small projects with innovative ideas that grew into large projects with solid communities. I've also witnessed the way dysfunctional communities can suck the energy from projects.

Conferences can be amazing experiences, with interesting people, great locations, and insightful talks. However, if you attend enough conferences, or the wrong conferences, you could succumb to one of the worst pandemics of our age. No, not "conflu"—death by PowerPoint.

One of the most daunting challenges for people switching from a familiar Windows or MacOS system to Linux is installing and configuring a driver. This is understandable, as Windows and MacOS have mechanisms that make this process user-friendly. For example, when you plug in a new piece of hardware, Windows automatically detects it and shows a pop-up window asking if you want to continue with the driver's installation. You can also download a driver from the internet, then just double-click it to run a wizard or import the driver through Device Manager.

Raspberry Pi 3 Model A+ is a smaller, cheaper, lower-powered Pi 3 and it's on sale now at just US$ 25. The newest Pi is ideal for projects in which you need the speed and processing power of the Pi 3 but can live without ethernet, multiple USB ports, and extra RAM.

For as long as GNU/Linux systems have existed, system administrators have needed to recover from root filesystem corruption, accidental configuration changes, or other situations that kept the system from booting into a "normal" state.
